GX-6 Intelligent Load Sensing Unit
The ISU™ building block: GX-6 is itself a complete weighing node — strain sensing, signal conditioning, temperature compensation, edge processing and CAN communication integrated in a 25 × 25 × 14 mm unit.
Distributed measurement. Edge processing. Centralized display.
Two GX-6 units are bonded onto the load-bearing area of each axle — typically one near each wheel, between the leaf spring and the wheel. All units talk over one CAN 2.0B bus to the NEW-T3000 in-cab terminal, which displays axle and total payload and can push data to the fleet platform via API.
- 2 units per axle (one per wheel side) — typical 3-axle truck = 6 units
- CAN 2.0B extended frames, 500 kbps, up to 32 units and 50 m bus
- No drilling, welding or structural modification of the vehicle
- Works with square-section axles; vehicle power isolated via matched supply module

NEW-T3000 — the industrial in-cab display
The NEW-T3000 is the human-machine interface of the system. Mounted in the cab, it shows live per-axle and total load, gives the driver clear feedback during loading, and hosts the guided zero / load calibration workflow used at install and re-calibration.
- Live total, axle and wheel load display
- Guided on-screen calibration and configuration
- Rugged industrial design for cab conditions
- Gateway between the GX-6 CAN network and fleet/cloud services
